    Hello, This series of products are designed for the one-time switch, so it is used for low frequency, if PWM is applied, we would recommend using lower than 300Hz, or for parts even <100Hz, you may relate to the ton/toff time of the part for details. Thank You

    Hello,

    Sure, I can help with that. The CY4534 EZ-PD eval kit is based on the Cypress EZ-PD CCG3PA USB Type-C and Power Delivery controller, which has a set of registers that can be accessed and configured through the EZ-PD BCR HPI (Host Processor Interface) Utility.

    The CCG3PA controller has a set of 256 registers, each of which is 16 bits wide. The registers are numbered from 0x0000 to 0x00FF in hexadecimal notation. The lower 8 bits of the register address determine which register is being accessed, and the upper 8 bits determine the type of access (read or write).

    To access the registers using the EZ-PD BCR HPI Utility, you will need to connect the CY4534 eval kit to your PC and open the HPI Utility software. The software provides a graphical user interface that allows you to read from and write to the registers.

    When you open the HPI Utility, you’ll need to connect to the CY4534 eval kit by selecting the appropriate serial port and baud rate. Once you’re connected, you can use the “Register Access” tab in the software to read from and write to the registers.

    You can find more information about the CCG3PA controller and its registers in the datasheet provided by Cypress. The datasheet includes a register map and descriptions of each register’s function and configuration options.

    Thank You

Hi all,

I am testing to configure node 2 and node 3 on module CAN1 to be linked to the inside can bus and out.

My final aim is to transfer some data on cun node 1- 2 and receive it on can nodes 1- 3 without any processing in the CPU.

no purifier configuration and messages to be transferred, no pack/ unpack function- just as simple as that loop back out.

so I set all needed configurations where I had the node working on normal mode( transfer and receive messages, filter, and messages defined), but also I removed the configurations of the filter and added to the configuration the needed flag

rc = canNodeConfig (& nodeConfig, reeCanNode);// set common configurations

* nodeSfr = IfxCan_getNodePointer (nodeConfig.can,nodeConfig.nodeId); nodeSfr->NPCR.B.LOUT = 1;

for both nodes 1- 2 and 1- 3.

what eventually happens is that I send from an outside source and it looks like the CPU receives (no errors on the bus) but the other bus has errors on it.

how can I be sure that the messages entered into that node? will interrupt for TX/RX receive?
what should I do to test it correctly?
is the setup OK for my purpose? (loop back out)?

Thank You

    Hello,

    Connected to the internal CAN bus and loop back the messages received on node 2 to node 3 without any further processing by the CPU.

    To accomplish this, you can configure both nodes to operate in normal mode and enable loopback mode for node 2 using the LBP bit in the NPCR register. The LBP bit sets the loopback mode for the node, allowing it to receive its own transmitted messages.

    Here are the steps you can follow:

    • Configure both nodes to operate in normal mode as you have already done.
    • Enable loopback mode for node 2 by setting the LBP bit in the NPCR register to 1.
    • Transmit a message from an external source to node 2.
    • Verify that node 2 receives the message by checking the RMC and NCR registers.
    • Verify that node 3 receives the same message by checking the RMC and NCR registers.

    You can also use interrupts to receive messages on the nodes. You can enable interrupts for receive and transmit events and write interrupt service routines (ISRs) to handle the events. When a message is received, the corresponding receive interrupt will be triggered, and the data can be read from the received message object.

    Kind Regards,

    Alex Thomas

    Hi, For enabling the automatic password sequencing you can write 1 to bit PAR of WDTCPUyCON1 (or WDTSCON1 for safety watchdog) Register. For example, if you want to enable automatic password sequencing for CPU0 you can do it like this (IfxScuWdt_getCpuWatchdogPassword()); = 1; (IfxScuWdt_getCpuWatchRead more

    Hi,

    For enabling the automatic password sequencing you can write 1 to bit PAR of WDTCPUyCON1 (or WDTSCON1 for safety watchdog) Register. For example, if you want to enable automatic password sequencing for CPU0 you can do it like this

    (IfxScuWdt_getCpuWatchdogPassword());
= 1;
(IfxScuWdt_getCpuWatchdogPassword());

    After enabling this point the password changes automatically after each password check and follows a pseudorandom sequence based upon a 14-bit Fibonacci LFSR with characteristic polynomial x14 x13 x12 x2 1 as you said. So each time you have to calculate the new password grounded on this sequence.

Dear All,

We’ve made a class d system, based on IRS2092 CHIPSET.

It’s an amp of 2000W system and we use MOSFET of Onsemi FDP51N25.

We’re looking to change this to Infineon MOSFET with part number IRFB4332.

Please suggest can it’s one to one replacement from FDP51N25 TO IRF4332.

    Hello,

    The IRFB4332 is a suitable replacement for the FDP51N25 MOSFET in your Class D amplifier system. Both MOSFETs are N- channel devices and have such voltage conditions, with a minimum VDS of 250V.

    The IRFB4332 has a just lower RDS (ON) value than the FDP51N25, which means it’ll dissipate less power when conducting. This can potentially result in better effectiveness for your system.

    However, it’s important to note that the IRFB4332 has an advanced pulsed drain current (Id) level of 60A compared to the 51A level of the FDP51N25. This means that if your system operates at very high current levels, you may need to ensure that the IRFB4332 can manage the current without breaking its maximum levels.

    Overall, make sure to double-check the specifications and ensure that the MOSFET can manage the demands of your specific application.

    Thank You

Hello,

I’m trying to come up with a system to perform wear leveling in the Dflash EEPROM (AURIX TC265).

After going through the user manual, example code, and a few other posts in this forum, the correct way of writing to Dflash is (Please correct this if it’s wrong)

1. Erase entire sector( 8KB)

2. Enter Page mode with the page address

3. Load data to be written

4. Write page/ write burst.

Repeat steps 3 and 4 until the needed amount of data is written to DFlash.

The data that I want to write to Dflash isn’t further than 32 bytes in total. So, I was looking for a technique to spread out these 32 bytes written in the logical sector( 8192 bytes) itself every time I need to store a new dataset. Is this possible? Or am I limited to spreading out my writes across sectors and not on the page level, as erase command works only on the sector level and not on the page level?

Thanks

    Hi Vikas. Yes, that is a common issue. You do not need to fill the whole sector at once; you can incrementally write pages until the industry is full.

    Hi Vikas.

    Yes, that is a common issue. You do not need to fill the whole sector at once; you can incrementally write pages until the industry is full.

    The tricky part is avoiding the erase disturb effect and dealing with the possibility of word line failures, as described in 10.8.3.1 Robust EEPROM Emulation on page 1000 of tc26xB_um_v1.3.pdf. For example, it’s impossible to have one set of static manufacturing data written once in DF0, and one set of dynamic data; all data must be periodically rewritten to avoid erasing disturbs.
